ALVE LOCK.

Application filed September 4, 1924. Serial No. 735,768.

To all whom it may concern:

Be it known that I, ADOLPH Mains, a citizen of the United States, and aresident of Brooklyn, county of Kings, and State of New York, haveinvented certain new and useful Improvements in a Valve Look, of

which the following is a specification.

This invention relates to an improved valve lock, and more particularly,in a preferred embodiment thereof, is designed for application anduse inconnection with mo: .tor driven vehicles whereb the floizs or supply offuel, such as gasoline, for the op 'eration of the motor, may beprevented and the possibility ofv theft or operation of .the

a minimum. 1 a

It is another object of my invention to provide a valve lock for theabove purpose, which can be easily and quickly appliedto vehicle byunauthorized persons, reduced to the modern motor vehicle withoutnecessitating' any radical structural changes therein, and which,'whenapplied, cannot be detached or removed from its operative position.

In a simple and practical embodiment .of

the device, a tumbler pi'n cylinder lock is associated with a rotaryvalve slug-interposed inthe fuel supply line, sa' lock having a keyreceiving barrel mounted for1ro tary and axial movement and said barreland the'valve plug being provided with coacting means, whereby when thebarrelfis rotated to 'a predetermined. position and then "shiftedaxially, it is automaticallyzconnected with the valve plug whereby thelatter may be moved to its open or. closed positions. e v I With theabove and other objects injlview,

the invention consists in the improved ,=?$1Ye-- lock, and in the form,construction and relative arrangement of its several; parts as" will behereinafter more fullydescribed, il'- lustrat'ed in'the accompan ing.drawing,-and"i I ya'sj-to, frictionally engage the beveled faces *of thecollar withcthebeveled surfaces of subsequently incorporateiniilzthepsubloind claims. I -1 In the drawing wherein, 1 11M. a simpleand desirable construction'and' ;iflwhich similar referencecharactersdes'ig nate corresponding parts 'throughout,-=t several views:Figure 1 is a sectional view showmglmy improved lock valve arranged inthe fuel supply pipe of a motor vehicle;

Figure 2 is a sectional view taken on the line 2-'2cof Figure 1;

Figure 3 is a' view. similar to Figure 1 showing the valve in openposition;

Figure-4 is a plan view;

Figure 5 isa detail end "elevation of the barrel of the cylinder lock;and Figure 6 is a similar view of the rotary valve member.

Referring in detail to the drawing, wherein I have shown the devicemounted and arranged in operative position on the board B above theaccelerator pedal of a motor vehicle, the valve body 5 which may be ofany preferred form or shape, is provided absolute fluid-tight connectionbetween the pipe sections and thenipples 7, I provide each pipe sectionin s aced relation to itsend with an annular ange or collar of V shapeform in ,cross-section, said collar having theoppositely beveledsurfaces 9. Each nipple .7 is provided with-- an internal shoulder 10againsti which the end of one of the pi e'sections 8 seats, while one ofthe beveled aces.9 of the collar on said ipe section seats against thechamfered or ev-,

.eled surface 11,on'the end of said nipple. The nipple- 7 .is exteriorlythreaded to re; :ceiyeithe internally threaded coupling memher-12, oneend of which is provided with an internal beveled face 13 for engagementtviththe iother beveled face 9 of the collar lim thei pipe section 8,Thus vit will be ap-' p ai'ent 'that. when the coupling member 12 Isscrewed up tightly upon vthe nipple 7 so the -con ling member andthenipple 7, a fluid-tig't connection is secured,

which is intersected centrall of the valve body by the chamber 15 whicreceives the The valve body- 5 is formed-with a longi-'tudinallyextending fluid passage or bore rotary valve plug or member 16,said valve member having a port 17 extending transversely therethroughin the plane of the passage 14.

The valve chamber 15 at one 'of its ends opens into a recess 6 formed inthe upper face 6 of the valve body. A cylinder lock the sleeve 19 beingformed with an out- Wardly projecting beveled flange 22 to coact with abeveled face formed on the plate 21 at one side of the opening therein.This plate is engaged in the recess 18 of the valve body and permanentlyfixed thereto by means of a plurality of driving screws, indicated at23. The other or upper end of the lock cylinder 18 has an out-turnedflange 24 formed thereon extending within the plane of the face plate20.

The cylinder 18 is formed with the usual eccentrically located opening25 therethrough, to receive the barrel 26, said barrel being providedwith the customary slot to receive the key 27. This barrel and the lockcylinder are likewise provided with the usual spring-pressed sectionaltumbler pins 28 with which the key 27 co-operates.

As herein shown, the barrel receiving opening 25 at the upper end of thelock cylinder is diametrically enlarged as at 29 to mov'ably receive anannular flange 30 on the end of the barrel and which permits of theaxial or longitudinal movement of said barrel relative to the cylinder.The wall of the barrel is provided with a U-shaped slot 30 thereinhaving circumferentially extending arms at its upper and lower ends. Apin 32 fixed in the cylinder 18 projects into this U-shaped slot andlimits the rotary and longitudinal movements of said barrel. At itslower end the barrel 26 is formed with a diametrically extending rib 33which is adapted for engagement in a slot 3 1 formed in the upper end ofthe rotary valve member 16, as will be more fully hereinafter explained.This rib and the valve member are also centrally provided with pocketsor recesses to receive the opposite ends of a coil spring 35 whichnormally acts to yieldingly hold the barrel in its normal position withthe rib 33 thereof out of engagement in the slot 34. In such normalposition, the rib 33 extends at a 90 angle with respect to the slot 34and the port opening 17 in the valve member is positioned at rightangles to the fuel passage 14, thereby preventing the flow of fuelthrough said passage.

In mounting the device in position on the board B, the cylinder lockwhich is rigidly fixed in position upon the body of the valve by theplate 21 and screws 23, is inserted upwardly through the opening in thefloor board, said plate and the upper surface 6 of the valve bodyengaging closely against the surface of said floor board. The valve bodyis provided with a plurality of threaded sockets at spaced points toreceive the bolts or screws 36 which extend downwardly through openingsin the face plate 20 and coinciding openings formed through the floorboard. Thus the device is rigidly secured to the floor board. It willalso be noted that it is impossible to detach the look from the Valve bythe removal of the screws 23, since the heads of these screws contactclosely against the underside of the floor board.

Having now described the several structural parts of my invention, theoperation thereof will be understood as follows:

In the normal position of the parts as shown in Figure 1, wherein thevalve member 16 is in its closed position, the fuel cannot pass throughthe passage 14 of the valve body from the vacuum tank to the carburetorof the vehicle and it will be obvious that unless the proper key isinserted into the lock barrel 26, said valve member cannot be moved toits open position. Aiso,-even if a key were inserted and the sectionaltumblers properly positioned to permit rotation of the barrel member,one unfamiliar with the manner in which said barrel must be operated,would in all probability, not be able to open the valve. In order tomove the valve member to open position, after the key is inserted asshown in Figure 1, it is turned to rotate the lock barrel through 90,said rotating movement being limited by the pin 32 engaging one side ofthe straight longitudinal portion of the slot 31 'in the wall of saidbarrel. Such rotation of the look barrel positions the rib 33 thereof inparallel relation with the slot or recess 34: in the end of the valvemember. The lock barrel is now lite forced inwardly against the actionof spring 35 so that the rib 33 is engaged in the slot 3e and therotation of the lock barrel then reversed, such movement being limitedby engagement of the pin in the end of the upper horizontal portion ofslot 31 in the wall of the lock barrel. In this latter reverse turningmovement of said barrel, the valve. member 16 is, of course, given a.quarter turn so that the port 17 thereof is brought into alignment withthe passage 14 through the valve body, thus permitting the uninterruptedflow of the fuel through said valve. In this inward axial'movement oftratedin Figure 3 of the drawings. It is,

' fore, be manufactured and sold at a nomiof course, understood thatwhen the owner of the vehicle'desires to lock the valve in closedposition, it is only necessary to reverse the above described operationsand then withdraw the key 27.

From the foregoing description considered in connection with .theaccompanying drawing, the nature of my present improvements and theseveral advantages thereof in practical use will be full understood. Ihave described the device as more especially designed foruse inconnection with the fuel supply pipe of a motor vehicle, but it will bemanifest that myiinvention might also be advantageously applied tovarious other analogous uses. It will be seen that the severalcooperating elements of my improved valve lock are few in number, simplein: form, positive and reliable in their operation and not liable togetout of order. The device may, therenal price. Since no radicalalterations are necessary in the structure of thevehicle in order toproperly apply a valve lockin operative ,POSltiOIl, such application ofthe valve may be readily made by the individual vehicle owner.

Ihave herein referred to the device as being applied .to-the floor boardof the vehicle, but it will be under? stood that the same might-also beotherwiselocated and connected in the fuel pipe supply line, as may bedeemed most iconvenient.

I have herein described an embodiment of the invention which in actualpractice I have found gives excellent results. Nevertheless, it 'Wlllbeunderstood that the device issusceptible of embodiment'in variousother alternative structural forms and I, therefore, reserve theprivilege of. resorting to all such legitimate changes inthe bodiedWithin the-S form, proportion and relativearran 'ement of the detailparts, as may be fairy emirit and scope of the invention as claim I 3"1.
